Currently I have a pretty complex project with as many as 5 different compositions. I'm using Edge Commons and some bootstrapping trickery to load the 5 compositions (each one represents a complex screen). It seems like the more compositions I load, the slower the project runs. Is there a way to unload a composition (or at least kill any cycles spent on that composition) when I'm done using it? Basically I'm looking for the ability to set 1 composition to active so it gets all the computers resources, and then when it's not active then to get none of the resources.
